Patent

CA 2462244

The present invention relates to a hydrophilic substance production method characterized in that polyvinylpyrrolidone-containing material wetted with an aqueous solution of a cationic polymer is treated with radiation. The invention makes it possible to produce material for blood treatment that prevents adsorption of blood platelets.

L'invention concerne un procédé de production d'une matière hydrophile, qui se caractérise par le traitement d'une matière comprenant un polyvinylpyrrolidone par rayonnement, la matière étant maintenue simultanément humide par une solution aqueuse contenant un polymère cationique. Grâce audit procédé, une matière pour le traitement du sang, inhibant le dépôt des plaquettes sanguines, peut être produite.
